To be 100% accurate, Heritage USA was not, despite the constant use of the phrase by the media an amusement park, nor a theme park. “Resort” would be a more accurate description; the property’s main feature was a four star hotel with a five star hotel partially built but abandoned when the scandal broke. There was the television studio where the PTL television shows were broadcast, a prayer center, a Biblical garden, several restaurants, a small shopping mall (featuring a cosmetics store bearing Tammy Faye’s name) and an outdoor amphitheater where a Passion Play was presented each evening. There was also a smaller “motor lodge” style motel and an area for RVs.
The only thing theme park-like about Heritage were the trams which transported visitors around the property and a small waterpark that featured an outsized swimming pool and a handful (fewer than a half dozen) water slides. When Jerry Falwell took over management of the PTL ministry and Heritage, he famously went down the highest of the water slides while fully dressed in a suit. But trams and a waterpark do not an amusement park make.
(Yes, I am actually speaking from first hand knowledge; my mother was a “lifetime member” of Heritage, and I joined her in two of her annual visits, including one shortly after the scandal broke. Truth be told, I’ve definitely vacationed in worse places.)
